Test N: The Power Running Board Module Does Not Respond To The Scan Tool
PINPOINT TEST N: THE POWER RUNNING BOARD MODULE DOES NOT RESPOND TO THE SCAN TOOL
Normal Operation
The power running board (PRB) module communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits
VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the PRB module. The PRB module shares the
MS-CAN with the instrument cluster (IC), the smart junction box (SJB), the heating ventilation air conditioning (HVAC) module (if equipped), the
audio control module (ACM), the rear entertainment module (RETM) (if equipped), the driver seat module (DSM) (if equipped), the satellite digital
audio receiver system (SDARS) module (if equipped), and the parking aid module (PAM) (if equipped). Voltage for the PRB module is provided by
circuit SBB19 (BU/RD). Circuit GD151 (BK/GN) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
PRB module
